  • Method for preparing dicarboxylic acids
    Patent number: 3979450
    Abstract: A method for preparing dicarboxylic acids by subjecting cycloolefins to ozonolysis in a medium of lower monocarboxylic acids so as to form an ozonalyzate; treating the ozonalyzate with a solution of hydrogen peroxide; passing the thus obtained mixture through a solid acid catalyst, such as an Amberlite IR-120 cation-exchange resin; and subjecting the thus obtained catalyzed product first to thermal treatment at a temperature of from 50.degree. to 80.degree.C and then to thermal decomposition at a temperature of from 90.degree. to 110.degree.C to form desired dicarboxylic acids such as succinic, suberic or 1,10-decanedicarboxy acids, depending on the starting cycloolefin, in a yield 98 per cent of the theoretical value and of 99.5 per cent purity.
